摘要:The well-documented rating inflation of incentivized reviews (IRs) can mislead consumers into choosing a product that they would otherwise not buy. To protect consumers from this undesirable influence, the U.S. Federal Trade Commission recommends that reviewers conspicuously disclose any material connection they may have with sellers. In theory, such disclosures safeguard consumers by motivating reviewers to be truthful and inducing consumers to discount inflated IR ratings. Our research finds...

摘要:We consider the classic stochastic multiarmed bandit problem with a constraint that limits the total cost incurred by switching between actions to be no larger than a given switching budget. For this problem, we prove matching upper and lower bounds on the optimal (i.e., minimax) regret and provide efficient rate-optimal algorithms. Surprisingly, the optimal regret of this problem exhibits a nonconventional growth rate in terms of the time horizon and the number of arms. Consequently, we disco...

摘要:We investigate how market participants price and manage counterparty credit risk using confidential trade repository data on single-name credit default swap (CDS) transactions. We find that counterparty risk has a modest impact on the pricing of CDS contracts but a large impact on the choice of counterparties. For contracts ineligible for central clearing, we show that market participants are significantly less likely to trade with counterparties whose credit risk is highly correlated with the...

摘要:Several features of automotive procurement distinguish it from the prototypical supply chain in the academic literature: pass-through pricing that reimburses suppliers for raw material costs, market frictions that prohibit cost transparency and imbue suppliers with pricing power, and contractual commitments that span multiple production periods. In this context, we formalize a procurement model by considering an automaker that buys components from an upstream supplier to assemble cars over sev...

摘要:Despite mixed evidence for the relationship between demographic diversity and creativity, we propose that observers hold a lay belief that demographic diversity increases creativity and apply this lay belief in judgments about teams and their creative work. Across eight preregistered studies (n � 5,530), we find that observers judge teams diverse in terms of race and gender to be more creative than teams homogeneous in terms of race and gender, including in incentive-compatible predictions ma...

摘要:Immigration has proven to be a major force driving entrepreneurial dynamics. In this paper I investigate how the geographical distribution of immigrants within a given country, and in particular the presence of enclaves, affects the relationship between immigration and entrepreneurship. I examine the impact of Polish immigration to Great Britain following the unprecedented migration wave caused by the European Union enlargement in 2004. I address omitted variable concerns by using information ...

摘要:We report experimental and quasi-experimental evidence from a sharing economy marketplace that transitioned from decentralized to centralized pricing. Centralized pricing increased the utilization of providers' assets, resulting in higher revenues but also higher transaction costs. Providers who were barred from accessing the price system made nonprice adjustments, including reducing the availability of their assets, canceling booked transactions, and exiting the market. Providers who retained...

摘要:In markets, such as those for airline tickets and hotel accommodations, firms sell time-dated products and have private information about unsold capacities. We show that competition under private information may explain observed phenomena, such as increased price dispersion and higher expected prices toward the deadline. We also show that private information severely limits the market power of firms and that information exchange about capacity increases firms' profits. Finally, we inquire into...

摘要:We study the problem when a firm sets prices for products based on the transaction data, that is, which product past customers chose from an assortment and what were the historical prices that they observed. Our approach does not impose a model on the distribution of the customers' valuations and only assumes, instead, that purchase choices satisfy incentive-compatible constraints. The uncertainty set of potential valuations of each past customer can then be encoded as a polyhedral set, and ou...

摘要:Project selection decisions are complex because they must balance not only financial returns, project risk, and fit with strategy, but also competitive circumstances. A rival's project development efforts provide two pieces of information: a market rivalry signal, indicating potentially heightened competition in a market, and a technological signal, indicating a possible solution to a problem in that market. We hypothesize that these signals affect a firm's likelihood of project selection in o...
